Older people working

It's not unusual in town. What? To see a lot of older people working. As South China Morning Post reported, about 18 per cent (around 1,3 million of the city's population) is aged  65 or older.
And  a lot of then are still working: 44,4 per cent of those aged 60 to 64.
Some are self employed, working in small stores or in tiny  stalls fixing watching and electronics.
Others are employed at the city's markets or keep the streets clean.
An increasing number are working at supermarkets, fast-foods outlets and more.
